A radar system with a radar sensor ( 10 ) which comprises a transmitting module ( 20 ), a receiving module ( 22 ) and a supply network ( 64 ), wherein the transmitting module ( 20 ) comprises a first plurality of partial antennas ( 26, 28, 30, 32, 34 ) and the receiving module ( 22 ) comprises a second plurality of partial antennas ( 46, 48, 50 ), and wherein the supply network ( 64 ) operates at least one partial antenna ( 30 ) of the transmitting module ( 20 ) together with at least one partial antenna ( 48 ) of the receiving module ( 22 ) in a first operating mode, to obtain a first, low angular resolution, and wherein the supply network operates one group of partial antennas ( 26, 28, 30, 32, 34 ) of the transmitting module ( 20 ) together with a group of partial antennas ( 46, 48, 50 ) of the receiving module ( 22 ) in a second operating mode to obtain a second high angular resolution. The radar system is characterized in that the supply network ( 64 ) operates at least one partial antenna ( 30 ) of the transmitting module ( 20 ) together with a group of partial antennas ( 46, 48, 50 ) of the receiving module ( 22 ) or a group of partial antennas ( 26, 28, 30, 32, 34 ) of the transmitting module ( 20 ) together with at least one partial antenna ( 48 ) of the receiving module ( 22 ) in a further operating mode.
